I have been having Sleep Parlysis for a few years now. I am now 24.
I remember the first time I had it it scared me near to death. My mind awoke during sleep, and it felt like someone was moving over, towards me, and I couldn't move to get away. I am not easily scared but I looked it up on the net and discovered more about SP.
After this, I had SP experiences where I had lucidly felt like I had fallen off of my bed, and was crawling around on the floor, but with everything blurred, or if you were super drunk and time was massively distorting and I was disorientated. Once I felt myself crawling over my bedroom floor, exiting my room and falling down the stairs. This wasn't just like a normal dream, even like SP, but my mind thought I was -actually- moving around and I was scared that if I wasn't dreaming not to hurt myself. I was scared of falling out of a window or something or bashing into something in my room. Other times I just fall out of bed and manage to struggle with myself to wake me up from the experience. This, the scariest most vivid type of dream I have had happened a few times about 6 years ago. I slept walked a couple of times during this period too, each time I had been out drinking the night before, once I opened my parents bedroom door startling them, and told them I was going to the pub (this was about 6am), then apparently I just walked back to my bed and back to sleep.
Since then I have encountered sleep paralysis a fair bit in the last 6 years. Sometimes I get it once or twice a week, but sometimes go a couple of weeks or months without it. It usually occurs as I am drifting off to sleep in the morning, having already woken, and as I'm trying to get back to sleep, that is prime time for REM and SP, especially if I'm laying on my back. Sometimes I get it literally every time I start to fall asleep for about 3 or 4 times, and then either have to get up from bed or lay on my side to get rid of it. When I get it now, I realise I'm in an SP state, and basiclaly just try as hard as I can to open my eyes. Sometimes this can be very frustrating, sometimes scary as I can't breathe but because I know I'm in SP it just gets annoying now. I usually get it more when I am not smoking marijuana. I have found that smoking marijuana makes me alot less prone to SP, strange/scary dreams, lucid dreams, sleep walking and nightmares.
When I am next in SP, I would like to explore it a bit further. I think I am ready. I read up alot about this subject and people with similar experiences when it first happened to me, but I am interested in being able to control a dream, or astral project if you will. and OBE would be fine too.
